Leng S.

I am an Embedded Hardware and PCB Design Engineer with extensive experience developing reliable electronic products from concept through production. My expertise includes schematic design, multilayer PCB layout, high-speed interfaces (USB, Ethernet, MIPI, DDR), RF and wireless systems (Wi-Fi, Bluetooth, LoRa), power management, battery-powered devices, and embedded systems based on STM32, ESP32, Raspberry Pi, NXP, Nordic, and Rockchip platforms. I use Altium Designer and KiCad to create manufacturable, production-ready designs with a strong focus on signal integrity, EMC/EMI, and Design for Manufacturing (DFM). I have successfully delivered projects in IoT, industrial automation, medical, consumer electronics, robotics, and communication systems. I am committed to clear communication, meeting deadlines, and providing high-quality engineering solutions that help clients bring their products to market successfully.
